产品概述

Rp-01 是一款步进电机驱动的柱塞泵,容量固定为 6 ml,以陶瓷活塞与阀头实现流量切换。结构紧凑、密封可靠,适合对定量体积与洁净切换有要求的立体定向注射、灌流与微流控系统。

梯形丝杆(导程 1 mm)驱动 19.1 mm 额定行程、共 3820 步,单步分辨率 0.005 mm(约 1.5707 ul),线速 0.017–8.33 mm/s。单程运行时间自 500 rpm 时的 2.292 s 至 1 rpm 时的 1146 s。液体体积误差不超过额定行程的 1%,重复性误差 0.3%–0.7%;活塞内径 20 mm,驱动机构额定 300 万次无泄漏循环。通信速率 9600–115200 bps,协议为 ASCII 或自定义;含电磁阀与驱动的整机由 DC24V/1.5A 供电,重 0.462 kg。

典型应用

选型须知

  1. 6 ml 容量为固定值,Rp-01 适合单次柱塞行程可覆盖目标分配体积的应用;精度与重复性按额定行程计。
  2. 阀头可选单口、L 型双口或带阀双口,死体积分别为 1.45、1.387 与 1.716 ml,请按实际流路选择配置。
  3. 流路压力参考值:正向 0–0.5 MPa、过渡 -0.075~0.15 MPa、COM→NC/NO 负向 0–0.06 MPa;请对照工作压力选型。
